Unbound and hydraulically bound mixtures - Part 4: Test methods for laboratory reference density and water content - Vibrating hammer
未结合和水力结合的混合物 - 第4部分:实验室参考密度和含水量的测试方法 - 振动锤
This European Standard specifies a method for the determination of the relationship between the dry density and moisture content of a mixture when compacted using a vibrating hammer. It applies to mixtures used in road construction which contain not more than 30% by mass retained on the 20 mm test sieve.
